LOUIS GUIENOT, OF BALTIMORE, MARYLAND.

Specification forming part of Letters Patent No. 161,507, dated March30, 1875; application filed January 19, 1875.

To all whom it may concern:

Be it known that I, LOUIS GUIENOT, of Baltimore city, State of Maryland,have invented a new and Improved Fastening for Bedsteads and all kindsof frame-work; andI do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawing forming a part of this specification, in which-Figure 1 is a side elevation of fastening; Fig. 2, section of Fig. 1through line a: 00; Fig. 3, detail of the bolt and nut; Fig. 4, detailof the plate E; Fig. 5, section of bolt through line 3 y of Fig. 3.

This invention relates to an improved fastening for bedstead-rails, andfor all kinds of frame-work in general in which the parts are to bedetachably connected. It consists in a short bolt, having at one end ascrew-thread and nut, and a squared end to receive a wrench, and at theother an angular groove. Said bolt is placed longitudinally in oneportion of the frame, and is held therein by the nut, which engages withthe side of a recess, the grooved end of the bolt entering a detacha bleplate in the other portion of the framework, which said plate isprovided with a lug or extension which moves in the said groove, and,when the bolt is turned, draws and locks the two portions of theframe-work securely together, the peculiar arrangement of the nut withrespect to the other devices admitting of the tightening of the lockingdevices as they may from time to time become loose from wear.

1n the drawing, A represents the end of a bedstead-rail, and B a portionof the headboard. 0 is the bolt placed longitudinally in the portion A,which is recessed at c to accommodate the nut b, and receive the wrenchfor locking or unlocking the devices. D is the angular groove in the endof the bolt 0, which operates upon the same principle as a bayonet-slot.E is a small detachable metallic plate, which is perforated with a holethe size of the bolt 0, and provided with a lug, c, which moves in thegroove D, and locks the devices. This said plate E is made entirelydetachable from the rest of the devices, and is inserted loosely in amortise, d, in the portion B.

The operation of this device is as follows: The plate E is inserted inits mortise, and the bolt 0 arranged in the piece A, with the nut 1)upon the screw-thread in the recess. The parts of the frame A and B arethen brought together, and the grooved end of the bolt made to enter theplate E. The said bolt is now turned by means of a small wrench, and

the groove engaging with the lug upon the plate E, thereby drawing andlocking the parts of the frame securely together, the nut b andscrew-thread upon the bolt serving to tighten the devices when they maybecome loose, without separating the parts.

I am aware of the fact that it is not new to employ an angular grooveand apin to fasten bedsteads, and that a longitudinal bolt has been usedsomewhat similar to mine. I, therefore, disclaim such inventions.Devices heretofore employed, however, have no means of subsequentadjustment after once looked, and have to be taken to pieces if this isnecessary. It will be observed that my fastening obviates thisdifficulty, and makes a uniformly tight joint.

The devices, as thus described, may be used for bedsteads, fastening theparts of heavy picture-frames, the construction of portable houses, andnumerous other uses to which it may be applicable.

Having thus described my invention, what I claim as new is-- The plateE, having lug c, and loosely fitting a mortise in the rail A, incombination with the bolt (J, fitting a hole in the rail B, and havingan angular groove, D, at one end, and a screw-thread and nut at theother end, whereby the partsAB can be drawn together and looked, as alsothe locking device adjusted without separating the parts, substantiallyas described.

The above specification of my invention signed by me this 15th day ofJanuary, 1875.

L. GUIENOT.
